Pulping machine for corrugated board production

Abstract

The pulping machine for corrugated board production comprises a box body, a shell is installed at the bottom of the box body, supporting bases are installed at the four corners of the bottom of the shell, a first circular ring filter plate and a second circular ring filter plate are installed at the bottom of the inner side of the box body from inside to outside, and a fixing base is installed at the top of the first circular ring filter plate. A circular ring plate is movably connected to the inner side of the fixing seat, a rotating rod is rotatably connected to the center of the bottom of the box body, and a stirring mechanism is mounted at the bottom of the box body. Due to the fact that the filtering holes of the first circular ring filtering plate are larger than the second circular ring filtering plate, the finer fiber pulp faces the outer side of the interior of the box body, rotation of the first stirring frame and the second stirring frame can continue to stir the pulp, certain outward pushing force is generated between the stirring frame and the pulp in the stirring process, and the pulp can be evenly stirred. The slurry with fine fibers can quickly penetrate through the circular ring filter plate I and the circular ring filter plate II, so that the separation of the slurry with different fiber sizes is realized.

Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, specifically a pulping machine for corrugated cardboard production. Background Technology

[0002] Corrugated cardboard is a sheet made of linerboard and corrugated paper formed by corrugating rollers. Corrugated paper, like ordinary paper, is made from pulp. Corrugated paper, also known as kraft paper or cardboard, is a common material for paper packaging boxes. It is lighter than wooden boxes, yet rigid, and easy to cut to size, and is used to protect other packaged products from damage.

[0003] Traditional corrugated paper production requires raw materials to be shredded in a shredder and then reacted with reagents to form pulp. The pulp raw materials usually separate into pulps of different fiber sizes. However, in the current corrugated paper production process, all these pulps of different fiber sizes are made into corrugated paper, resulting in pulp waste.

[0004] Therefore, it is necessary to provide a pulping machine for corrugated cardboard production to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pulping machine for corrugated cardboard production to solve the problems existing in the background technology. The technical solution of this utility model provides a solution that is significantly different from the existing technology, which is aimed at the problem that the existing technical solutions are too simple.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pulping machine for corrugated cardboard production, comprising a box body, a shell mounted on the bottom of the box body, support seats mounted at the four corners of the bottom of the shell, a first circular filter plate and a second circular filter plate mounted from the inside to the outside on the inner bottom of the box body, a fixed seat mounted on the top of the first circular filter plate, a circular plate movably connected to the inner side of the fixed seat, a rotating rod rotatably connected to the bottom center of the box body, and a stirring mechanism mounted on the bottom of the box body.

[0007] Preferably, a circular plate one is connected to the bottom inner side of the circular plate, and a through hole is opened at the top of the circular plate one at equal angles. A circular plate two with a through groove is installed on the top inner side of the circular filter plate one, and a cylinder that mates with the through hole is set at the top of the circular plate two at equal angles. A stirring rod is installed on the top outer wall of the rotating rod.

[0008] Preferably, the bottom of the circular plate is provided with an annular groove communicating with the through hole, and a toothed ring is installed on the outer wall of the circular plate.

[0009] Preferably, the stirring mechanism includes a stirring plate installed at the bottom of the outer wall of the rotating rod, an annular plate fixed to the inside of the box is installed on the top of the second annular filter plate, a stirring frame is installed at the gap between the two ends of the first annular filter plate and the second annular filter plate, and a stirring frame is installed at the gap between the second annular filter plate and the two ends of the box.

[0010] Preferably, the shafts of the first and second stirring racks extend into the interior of the housing, and the bottom of the rotating rod extends into the interior of the housing. The rotating rod and the shafts are connected by a transmission assembly.

[0011] Preferably, a discharge pipe along the same axis is installed at the bottom of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Because the filter holes of the first annular filter plate are larger than those of the second annular filter plate, the finer fiber slurry tends to be directed towards the outer side of the chamber. Furthermore, the rotation of the first and second stirring racks not only continues to stir the slurry but also exerts a certain outward thrust during the stirring process. This allows the slurry with fine fibers to pass through the first and second annular filter plates more quickly, thus achieving the separation of slurries with different fiber sizes.

[0024] Please see Figure 1-7 A pulping machine for corrugated cardboard production includes a housing 1, a shell 2 installed at the bottom of the housing 1, support seats installed at the four corners of the bottom of the shell 2, a circular filter plate 3 and a circular filter plate 4 installed from the inside to the outside on the inner bottom of the housing 1, the filter holes of the circular filter plate 3 being larger than those of the circular filter plate 4, a fixed seat 5 installed at the top of the circular filter plate 3, a circular plate 6 movably connected to the inner side of the fixed seat 5, a rotating rod 7 rotatably connected to the bottom center of the housing 1, and a stirring mechanism 8 installed at the bottom of the housing 1.

[0025] like Figure 1-7 As shown, a circular plate 9 is connected to the bottom inner side of the circular plate 6. A through hole 10 is opened at the top of the circular plate 9 at equal angles. A circular plate 11 with a through groove is installed on the top inner side of the circular filter plate 3. A cylinder 12 that matches the through hole 10 is set at the top of the circular plate 11 at equal angles. A stirring rod 13 is installed on the top outer wall of the rotating rod 7. The circular plate 9 can collect the crushed raw materials and reagents together inside the circular plate 6 to react. The stirring rod 13 stirs the raw materials to form a slurry. The slurry can be transported to the bottom of the box 1 by controlling the separation between the cylinder 12 and the through hole 10.

[0026] like Figure 1-7 As shown, the bottom of the circular plate 9 is provided with an annular groove 14 that communicates with the through hole 10. A toothed ring is installed on the outer wall of the circular plate 9. The gear is controlled to rotate by the existing drive equipment, which drives the toothed ring to rotate. This allows the circular plate 6 to rotate, which in turn drives the cylinder 12 to slide inside the annular groove 14 and expose the through hole 10. The resulting slurry will then enter the inner side of the circular filter plate 3 through the through groove opened in the circular plate 11.

[0027] like Figure 1-7 As shown, the stirring mechanism 8 includes a stirring plate 801 installed at the bottom of the outer wall of the rotating rod 7, an annular plate 802 fixed to the inner side of the box body 1 installed on the top of the second annular filter plate 4, a stirring frame 803 installed at the gap between the two ends of the first annular filter plate 3 and the second annular filter plate 4, and a stirring frame 804 installed at the gap between the second annular filter plate 4 and the two ends of the box body 1. Since the filter holes of the first annular filter plate 3 are larger than those of the second annular filter plate 4, the finer fiber slurry is directed towards the outer side of the box body 1. Furthermore, the rotation of the first stirring frame 803 and the second stirring frame 804 not only continues to stir the slurry, but also exerts a certain outward thrust on the slurry during the stirring process, allowing the slurry with fine fibers to pass through the first annular filter plate 3 and the second annular filter plate 4 more quickly, thus achieving the separation of slurries with different fiber sizes.

[0028] like Figure 1-7 As shown, the shafts of the first stirring rack 803 and the second stirring rack 804 extend into the interior of the housing 2, and the bottom of the rotating rod 7 extends into the interior of the housing 2. The rotating rod 7 and the shaft are connected by a transmission assembly 15. The transmission assembly 15 can drive the first stirring rack 803 and the second stirring rack 804 to rotate by rotating the rotating rod 7. The rotation of the rotating rod 7 can be controlled by a motor in the prior art, and the motor can be set at the bottom center of the housing 2.

[0029] like Figure 1-7 As shown, a discharge pipe 16 with the same axial direction is installed at the bottom of the shell 2. The discharge pipe 16 can separate the separated slurry separately.

[0030] Working principle: During use, the circular plate 9 allows the crushed raw materials and reagents to accumulate inside the annular plate 6 for reaction. The mixture is then stirred by the stirring rod 13 to form a slurry. By controlling the separation between the cylinder 12 and the through-hole 10, the slurry is transported to the bottom of the housing 1. A drive device controls the gear rotation, which in turn rotates the gear ring, thus adjusting the rotation of the annular plate 6. This causes the cylinder 12 to slide inside the annular groove 14, exposing the through-hole 10. The resulting slurry then enters the inner side of the annular filter plate 3 through the through-slot in the circular plate 11. Because the filter holes in the annular filter plate 3 are larger than those in the annular filter plate 4, finer fiber slurries tend to flow towards the inner side of the filter plate. The rotation of the mixing rack 803 and the mixing rack 804, located on the outside of the housing 1, not only continues to stir the slurry but also exerts a certain outward thrust during the stirring process. This allows the slurry with fine fibers to pass through the annular filter plate 3 and the annular filter plate 4 more quickly, achieving the separation of slurries with different fiber sizes. The transmission component 15 can drive the rotation of the mixing rack 803 and the mixing rack 804 by rotating the rotating rod 7. The rotation of the rotating rod 7 can be controlled by a motor, which can be located at the bottom center of the housing 2. The discharge pipe 16 can separate the separated slurries individually.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
